2 Claims.

This invention relates to the treatment of warp yarn and more especiallyto an apparatus wherein the individual ends of the warp are maintainedin a separated position while the same are traveling from one point toanother.

During processing, cotton yarns pass through various solutions and aresubject to many treatments which tend to cause the adjacent ends in thewarp to stick or adhere to each other. As a means for separating theseends, it is a conventional practice to pass the warp through a reed,which reed comprises a plurality of spaced splits between which the endstravel. When adjacent yarn ends are adhesively secured together for aconsiderable distance and are caused to pass on opposed sides of a splitin a reed, the ends will often break before becoming separated, andthereby make it necessary to repair the broken ends.

As another example of the conventional practice, let us consider theprocessing of yarn for thread. In this process the gassing, mercerizing,

dyeing, drying, glazing, and waxing are all handled in warp form. Inmany instances each warp has 378 ends, and each end is 6,000 yards long.After the mercerizing, drying, dyeing, glazing, and waxing arecompleted, it is usually necessary to perform a quilling operation whichseparates the ends of the warp by a reed and winds each individual endon a separate package.

Sometimes, as heretofore stated, difficulties are encountered in thisquilling operation because the above-mentioned operations tend to causethe yarn ends to stick together so that they do not easily separate whenpassing through the reed. Heretofore, in order to overcome this stickingor adhering of the adjacent ends, the operator or quiller has beenaccustomed to rake or vibrate the warp ahead of the reed by taking anempty quill or stick and moving the same, back and forth, transverselyof the moving warp. Usually this warp is about 12 feet in width, andconsequently, it is impossible for one operator to rake the entire widthof the warp. As a result, some of the adhered ends break while passingthrough the reed.

It is an object of this invention to provide an automatic warp vibratorfor separating the individual yarnends prior to the same passing throughthe reed.

It is another object of this invention to provide a transverse rakehaving a plurality of flexible teeth therein, which teeth are adapted tobe disposed adjacent the moving warp and which,

-when moved transversely thereof, will tend to vibrate the individualends and maintain them in a separated state.

It is another object of this invention to provide a toothed rake of theclass described, with means for swinging the rake in an arc so that theindividual teeth will penetrate the warp at a constantly varying depth.During this penetration, the ends of the teeth move from a positioncompletely above the warp to the point of maximum penetration.Therefore, each tooth strums the individual ends, releasing the sameapproximately one at a time as it moves upwardly from its lowermostposition to its uppermost position.

It is another object of this invention to provide a yarn vibrating meansof the class described having means for adjusting the height of thevibrating means relative to the warp, and also having means foradjusting the amount of transverse arcuate travel of the vibratingmeans.

Some ofthe objects of the invention having been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawings in which:

Figure 1 is a side elevation of a textile quiller with my improved warpvibrating apparatus associated therewith;

Figure 2 is an enlarged sectional detail ViewA taken along the line 2-2in Figure l illustrating the stroke adjustment feature;

Figure 3 is a transverse vertical sectional view taken along the line3-3 in Figure 1, showing the rake or yarn vibrating means in lowermostbold Vline position and uppermost dotted line position;

Figure 4 is a sectional view taken along the line 4-4 in Figure 3showing a detail of the connection between the rake and its supportingmeans;

Figure 5 is an exploded isometric view of one end of the rake and thesupporting means therefor;

Figure 6 is a sectional view taken along the line 6-6 in Figure 5,showing the means employed for mounting eacn of the flexible yarnlingers in the rake. A

Referring more particularly to the drawings, the numerals I 0 and IIdenote the side frames of a quiller, which quiller has conventionaldrums I2, drive belts I 4, whorls I5, and quills I6, said quills beingadapted to have yarn ends I'I wound thereon. This quiller also has aconventional reed I9, a waxing roller 20, and a guide roller 2|.

In the processing of yarn it is usually in a warp form prior to passingthrough this machine. For the sake of clearness, this warp will bebroadly designated by the reference character 22. As the warp moves fromleft to right in the direction of the arrow in Figure 1, it passesthrough reed I9, over waxing roll 20, over a guide roll 2l, and thendownwardly onto quills I6. When the warp leaves the guide roller, theends I1 follow a divergent path to individual quills I6. As the drums I2are rotated, the individual yarn quills I6 are likewise rotated throughthe medium of belts I4 and whorls I 5 to thereby wind the individualends I1 there around.

Very often, the ends I'I of the Warp 22 become adhered to each other andare not easily separated by the splits in the reed I9. For this reasonit is necessary to constantly strum or vibrate the individual ends I1 ofthe moving warp so that the same will be maintained in a separatedposition, thus permitting the ends to easily pass through the reed I9.Figure 3 shows the position of the individual ends I1 in warp 22 priorto the same reaching the reed I9. This warp will vary in width, and isusually too wide for one operator to manually vibrate all of the `endsand prevent some of the adhered ends from reaching the reed I9 in anunseparated condition. In order to insure that all of the ends I1 in thewarp 22 will be constantly vibrated, uniformly -and automatically, atransversely disposed rake,

broadly designated by the reference character 26, has been provided.This rake 26 comprises a horizontally disposed bar 21, which bar isrectangular in cross-section and has its lower edge disposedsubstantially in parallel relation to the warp 22. Also this bar ispositioned transversely of the warp and has a plurality of flexible loopteeth 29 projecting downwardly from the lower -i 29, there being asupport 29 adjacent each side of the nger or tooth 2S for the purpose ofsupporting that portion of the finger immediately below bar 21 whilethev finger is deflected during its movement across the warp. Thedoubled ends of the finger 28, together with the two associatedreinforcing supports 29, are secured in the bar 21 by any suitable meanssuch as semi-circular dowel pins Sil. (See Figures 5 and 6.) rIhesupports 29 are extended downwardly for a substantiai distance below thebar 21 alongside the opposed sides of the looped finger 28 andconsequently, as the finger 28 is deflected, rst in one direction andthen in another as it moves transversely of the warp, the finger will becaused to bend about a longer radius and therefore, will not becomefatigued as quickly as would be the case were the reinforcing splints 29not provided.

It can be seen by observing Figure 3 that these fingers are spaced alongthe bar 2,1 so that the lower ends thereof will penetrate the warp atvarying depths while being moved from bold to dotted line positions. Itis to be understood that the dotted line position of the rake 26illustrates the position at one end of thefrake swing, whereas the boldline position illustratesl its midway ofi the swing. The rake will swingas far to the left of the warp 22 in Figure 3 when itoscillates to theleft as the rake is shown in dotted line position to the right.

Each end of the bar 21 has a metallic plate 35 secured thereto by anysuitable means such as bolts 26. The plate 35 and the end of the bar 2 1have a hole 31 therein, which hole is penetrated by a collar 38, saidcollar having integral therewith a flange 39. The collar 38 is providedwith a hole 40 which receives a bolt 4I when the parts are in an erectedposition. By observing Figure 4 it can be seen that the restrictedportion of collar 3B extends the entire length of hole 31 and thuspenetrates the bar 21 and the plate 35. The small end of collar 38 isadapted to fit against a hanger 43, and is held in position by means ofbolt 4I, wing nut 5i) and a washer 53, said bolt being adapted topenetrate a slot 5I in the hanger 43. This type of construction permitseach end of the bar 21 to be pivotally secured to the lower ends ofhangers 43 without any binding between the face of the hangers and theface of plates 35,

'or without any binding between the flange portions 39 and the faces cfthe bar 21.

This construction also permits the elevation of the rake 26 to be variedto suit operating conditions. For example, if it is desired that thefingers 26 penetrate the warp 22 a very slight amount, the wing nut 59may be loosened and the rake 25 raised accordingly; or if desired toentirely lift the rake out of Contact with the warp to a non-obstructingposition, this may be done also by manipulating the wing nut and movingthe rake 25 to the upper extremities ofv slots 5I.

The upper ends of hangers 43 are pivotally secured as at 5ft and 55 tobrackets 56 and 51 respectively, said brackets 56 and 51 being supportedby quiller frames l0 and II. In order to cause the hangers 53 tooscillate `about pivots 54 and 55, it is necessary to provide scmesuitable means such as shown in Figures 2 and 3. The shaft of pivot 5ftextends through the upper end of bracket 55, and the projecting end ofthis shaft has a laterally extending lever 59 keyed thereon.

Lever 59 has a slot 56 therein which is penevtrated by a bolt 6I', saidbolt having a head portion 62 abutting one face of the lever 59 and awasher 63 abutting the opposite face. A nut 64 is threadably secureduponl the end of the bolt 6I which projects beyond the washer, and thusthe bolt is adjustably secured in the slot 6i.

Bolt 6I also has a. larger projecting portion 66 extending from the headportion 62 and laway from the lever 53. Around this portion 66 a fitting61 is mounted, said tting extending downwardly and having pivotallysecured thereto as at 69 the upper end of a link 19. It is seen that thelongitudinal axis of portion 66 is disposed substantially at rightangles tothe longitudinal vaxis of pivot 69, and therefore, a universalconnection is provided between lever 59 and link 19.

The lower end ofv link 1'0 has a tting' 1I secured thereto. Pivotallysecured to this link 1I asat 12 is a second fitting 13, said fittingyE3-being pivoted as at 14' to a sprocket-wheel 15'. Likewise, thelongitudinal axes of pivots 12 and 14' are disposed substantially atright angles to each other, therebyV providing a second universalconnection. Especial attention is' called to the fact that the pivot Itis eccentrically" located relative tothe stud shaft 16, which shaftserves'as -an axis of rotation. for sprocket .15. Figure 3 shows theImanner in. which stud shaft i6 is attached to the quiller framel I5.

Sprocket I5 has ai chainr 158 mounted thereon,

'and thisfch'ain isi mountedup'on' another sprocket 'I9 which is drivenby one of the drums I2 of the quilling machine. When the machine is inoperation, the drums I2 are driven by any suitable source of power, notshown, to cause the quills I6 to rotate, and thus draw the warp ends I'Iof warp 22 downwardly onto individual packages. During this winding thewarp 22 is passing eneath the transversely disposed rake 26, throughreed I9, over waxingr roll 2S, and over guide roll ZI. The rotation ofsprocket 'I9 will, in turn, impart rotation 'to sprocket 'I5 through themedium of chain i8. It is therefore seen that as sprocket 'I5 rotates,the link 'I will be reciprocated up and down, thereby causing thehangers 43 to oscillate about pivots 54 and 55. This oscillation ofhangers 33 will cause the rake 26 to swing back and forth and thus causethe ngers 28 to strum or vibrate the individual yarn ends IT to separateany ends Il which may be stuck together.

Figure 3 clearly illustrates by arrows the approximate path of travel ofthe lower ends of iingers 23. In the bold line positions, the lingers 28are penetrating the Warp 22, the maximum amount for this particularadjustment of the rake. When the rake swings to right-hand dotted lineposition, it follows the arcuate path of the arrows and, at the sametime, gradually rises out of the warp, releasing the warp ends one at atime. When the rake reaches the end of its stroke, all of the ends havebeen released by each tooth 28, at which time the lower end of eachtooth is disposed above the Warp. During the swing in the oppositedirection, the teeth gradually move downwardly to bold line positionthrough the warp 22, and then the teeth again gradually rise until theyassume an elevation at the left of the warp substantially the same asshown in dotted lines to the right.

It is therefore seen that I have provided a simple and ecientVautomatic: means for maintaining the ends of yarn in separated orunattached positions. Also means have been provided whereby the lengthof the stroke and the amount of penetration of the warp can be regulatedas desired. By providing these :Ilexible iingers 28, the vibration ofthe warp can be effected without any material damage thereto.

A suitable board or cover is provided directly beneath the warp 22 andrake 26 so that the packages of yarn therebeneath will be shielded fromdirt, dust, and lint which. falls from the Warp.

In the drawings and specification, there has been set forth a preferredembodiment of the invention and although specific terms are employed,they are used in a generic and descriptive sense only and not for thepurposes of limitation, the scope of the invention being dened in theclaims.
